how Generate QR Code with complex data like contact information?

Question

Now I generate QR Code with simple text and for that I use below demo project.
IOS_QR_Code_Generator

And for generating QR code:

 NSString *code = @"JAY RAPARKA SIMPLE Encoding string";

 Barcode *barcode = [[Barcode alloc] init];

 self.view.backgroundColor = [UIColor whiteColor];

 [barcode setupQRCode:code];
 ivQRCode.image = barcode.qRBarcode;

Right now I just encode "JAY RAPARKA SIMPLE Encoding string" this simple text but I want to generate QR code for more complex data like (Contect information, link/URL, account balance on the base of id,etc..). So please any one done this earlier than please help me.

Thank you!

For decoding I use ZBar sdk and it also works properly and encoding also work but I just want to generate QR for more data.

You can use this code

- (NSString *)vCardRepresentation
{
  NSMutableArray *mutableArray = [[NSMutableArray alloc] init];

  [mutableArray addObject:@"BEGIN:VCARD"];
  [mutableArray addObject:@"VERSION:3.0"];

  [mutableArray addObject:[NSString stringWithFormat:@"FN:%@", self.name]];

  [mutableArray addObject:[NSString stringWithFormat:@"ADR:;;%@",
                       [self addressWithSeparator:@";"]]];

  if (self.phone != nil)
  {
    [mutableArray addObject:[NSString stringWithFormat:@"TEL:%@", self.phone]];
  }

  [mutableArray addObject:[NSString stringWithFormat:@"GEO:%g;%g",
                       self.latitudeValue, self.longitudeValue]];

  [mutableArray addObject:[NSString stringWithFormat:@"URL:http://%@",
                       self.website]];

  [mutableArray addObject:@"END:VCARD"];

  NSString *string = [mutableArray componentsJoinedByString:@"\n"];

  [mutableArray release];

  return string;
}

OR you can generate String with saparator like,

NSString *str = "Name : Jay, Work : IOSDeveloper";

and after that saperate this using

NSArray *ary = [mystring componentsSeparatedByString:@","];

now you can use this ary with index.
